Subject: [PATCH] ASoC: Introduce 'fixup_controls' card method
Mime-version: 1.0
Content-type: text/plain; charset=UTF-8
Content-transfer-encoding: 8bit
Git-commit: df4d27b19b892f464685ea45fa6132dd1a2b6864
Patch-mainline: v6.0-rc1
References: jsc#PED-850

The new method is called just before the card is registered, providing
an opportune time for machine-level drivers to do some final controls
Amending: deactivating individual controls or obtaining control
references for later use.

Some controls can be created by DAPM after 'late_probe' has been called,
hence the need for this new method.
